The Creighton Model System is based on the daily, routine observation of various bio-markers that a woman makes throughout her day. A standardized chart, stamps and recording system are used daily (an app is available), giving insight into the different phases of a woman's cycle and gynecological health. In addition to allowing a couple to determine days of fertility and infertility, the Creighton Model can also help a couple identify the underlying causes that may be contributing to infertility. These factors may include endometriosis, PCOS, hormonal imbalances or ovulatory dysfunction. By understanding her body, her cycle, and her fertility, a woman can make informed decisions about her health and family planning. 


To learn the Creighton Model, a woman (couple) attends an Introductory Session which will equip her to begin using the system.  She then attends individualized Follow Up appointments (8) tailored to her specific reproductive category effectively and confidently learn to chart. The Fertility Care Practitioner assigned to the couple not only educates, but offers support the woman and her husband on their fertility journey emotionally, physically, and spiritually.
